The owners / operators of the other board are planning to sell it, or rather put it into someone else's ownership. They cannot get any money for it because it actually costs them money to run it. Nobody will pay them any money for it because of such ongoing costs. The current owners / operators of that board intend to be recognised as leaders of Unita Fartior, an organisation within the organisation of CUOSC. Their ambition is to gradually replace the board of CUOSC with themselves and their associates. But that is going to be a very long process, each board member is in place for the time taken to hold 3 consecutive AGMs, which is not quite the same as 3 years. It seems that an ANNUAL General Meeting does not have to take place once per year, the period between AGMs can be stretched. At the end of a CUOSC board member's 3 AGM tenure there is an election for that place on the board of CUOSC. Thus for all 12 CUOSC board members to face an election, involving other candidates, it could take quite a few years and the incumbents could well be re-elected. The recent block of members coming in via Unita Fartior could well diminish (impatient for change and intolerant of lack of change) and thus the hard-core long term members could still hold sway, the more so as time passes.
Of course the appeal of being in control of CUOSC is that since it holds 25.4% of Holdings it has the appropriate importance. If you are on the board of CUOSC you can regard yourself as being important. If you are the CUOSC representative on the 1921 or Holdings board you can regard yourself as being very important.
However, it is quite possible that any ownership change in Holdings will only be done if the new owner gets 100% of Holdings. That would render CUOSC to be not very important, which would ruin the ambitions of those who aspire to power. There would be fuck all power to chase.
